This calculator performs the decomposition of a number into its prime factors and lists all its natural divisors. Enter an integer between 1 and 1,000,000.
1) Relation to multiples of 6: Every prime number greater than 3 is always one less or one more than a multiple of 6.
Example: `71941` is 1 more than `71940` (multiple of 6).
2) Square minus 1 divisible by 24: For every prime number greater than 3, if 1 is subtracted from its square, the result is always divisible by 24.
Example: The square of `71941` is `5175507481`. Subtracting 1, we get `5175507480`. Note that `5175507480 ÷ 24 = 215646145`.
3) Difference of squares: Every prime number greater than 2 can be expressed as the difference of the squares of two consecutive natural numbers.
Example: `71941 = 35971^2 - 35970^2 = 1293912841 - 1293840900`
4) Sum of two squares: Every prime number of the form `4n+1` (where n is a positive natural number) can be expressed as the sum of two squares.
Example: `71941 = 146^2 + 225^2 = 21316 + 50625`, where `71941 = 4 × 17985 + 1`.
5) Form `4n+1` or `4n-1`: Except for the number 2, all prime numbers follow the pattern `4n+1` or `4n-1`, where `n` is a natural number.
Example: `71941` is of the form `4n+1`, where `n = 17985`.
